Gateway Agent

Controls at runtime the exchanges between your agents and the outside world: tool calls (MCP) and inter-agent communications (A2A). Every exchange is traced to produce proof.

What the agent does

๐Ÿ”Œ MCP interception

Runtime control of tool calls, between the agent and its real tools, reversible.

๐Ÿ”€ A2A interception

Visibility and control of agent-to-agent communications, where application firewalls are blind.

๐Ÿ“š Source validation

Verification of documents and RAG sources called before injection into the context.

๐Ÿšซ Actuation blocking

Refusal of dangerous actions triggered via a tool: exfiltration, unplanned calls.

๐Ÿงพ Chained audit trail

Every exchange sealed in SHA-256, enforceable proof under the EU AI Act (art. 12).

๐Ÿ›ก๏ธ Sovereign deployment

At the edge, no cloud dependency, no change to application code.

How it works

1

Interception

MCP and A2A exchanges pass through the gateway

2

Validation

Verification of source, content and intent

3

Decision

Allow, block or redact at runtime

4

Proof

Exchange sealed in the chained audit trail

Technical approach

AI reverse proxy

Inline gateway on the LLM flows, with no change to application code.

North-south MCP

Control of tool calls between the agent and its tools, reversible by disabling the route.

East-west A2A

Control of agent-to-agent traffic to cut cascading propagation.

Runtime detectors

Indirect injection, dangerous actuation, alarm masking, exfiltration.

SHA-256 chained trail

Enforceable proof of exchanges, usable in the event of an audit.

Sovereignty

On-premise or edge deployment, no data sent to the cloud.

Use cases

PRE-DEPLOYMENT

Exposure measurement

Quantifying the attack rate of agent-tool exchanges before production.

PRODUCTION

Runtime control

Reversible interception of MCP and A2A flows on an already-deployed system.

COMPLIANCE

Proof of exchanges

Chained audit trail of communications, aligned with the EU AI Act.

Secure your agents' exchanges

Submit your system, we return an exposure report with the measured attack rate.
